Application led November 22, 1926. Serial No. 150,095.'

VThis invention relates to tools and has special reference to a' toolfor driving out hub bushings and bearing cups. l

lThe principal object of the inventionis to provide, as a new article ofmanufacture, a novel toolfor driving out the bushings used in automobilewheel hubs, the tool being constructed of a single length of rod metal,preferably steel, and round in cross-V `,section as well as beingresilient in character; the length of rod being bent and forged toproduce the particular tool.

With the above and other objects in view as will be hereinafterapparent, the invention consists in general of certain novel details ofconstruction and combinations of parts hereinafter fully described,illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawings like characters of reference indicate likeparts in the several views, and: l Y

In the formation of this tool a suitable length of round steel rod istaken and bent centrally of its length` as at 10 so that there isprovided a pair of handle portions 11 which are circular incross-section and which contact throughout their length. At the bendthese handle portions are forged as by hammering, pressing or othersuitable shaping operation of like character, so that the combinedcross-sections of the two por#v tions appear substantially rectangular.`At

the same time the end at the bent portion is attened as at 12 to form a.striking surface for a hammer or other percussive implement. From thelhandle portions 11 thev rod is continued forwardly and divergingly, thediverging 'portion adjacent the handle being forged to form a pair offlat spring portions 13 whichareflatly rectangularin cross section withtheir widerl surfacesopposed so that they can readily spring towardandfrom each other. Forward of the spring portions 13 the rod iscontinued'in its.

regular circular cross section and is then terminated at each end inanjoutwardly inclined terminal portion 111.The end faces of theseterminal portions are beveled at an angle to the axes of the portions,the bevcling being such that the end faces lie inthe same plane.Furthermore, the outer sides of these terminal portions lare flattenedso that when-the handle' 11 is inserted through a hub and its bushingthese flattened vportions contact with the outer endof the bushing andyformcam surfaces yforcing the terminal portions 14 togethen These flatouter faces are indicated at 15 and the fiat beveled forward facesl at16. .'It vwill thus be seen that. the tool thus constructed is anarticle of manufacture formed from a single llength of rod forged andshapedy Jtoprovide a highly efficient bushingremoving tool.` i

so; 'Y

In the form shown in Figs. 7 and 8 the tool is made by bending andforming a rod as inthe form previously described but one of the springYportions 13 Vis formed, 'either by splitting or by welding a piece ofthe rod thereon, to' provide a ,thirdv spring portion 19 terminating ina portion 2O of the normal rodY cross section and having an-angularlydisposed end 21. (bviously', the Athree "'H spring portions and theirends will be evenly spaced to lie 120 degrees apart as shown in Fig. 8.f o

In'the form shown in Figs. 9 and 10 the tool is made in two parts, onepart being termed the inner part and being identical in form' andconstruction with the type shown .I

in the first siX figures ofthe drawing. The other or outer part islikewise formed from la single length of rod preferably of the samecross section as 4that from which the inner Vpart is formedl This secondlength of rod l is bent and forgedto provide an limpact receiving headportion 22 and a pair of handle portions 23 which lie in the groovesbetween the portions 11. Opposite the spring portions l13) the secondrod is Hatten-ed to provi'de spring portions-24 which terminateforwardly in'portions 25 of the normal rod cross section andhavingangled ends 26 like the ends 15. In this case the outer'portion has itslegs disposed in a plane ,at` right angles to the legs of the innerportion.

In Aeach ease it will be seen that Athelbasic construction is that shownin the first form.

In operation, as indicated above, the tool is passed through the hubhandle. end first until the surfaces 15 engage the outer end of thebushing. Then the handle is grasped and the tool pulled further throughthe hub. The usual notches inthe collars 16 of the hub 17 assist inguiding the tool and when the terminalportions 14 have pass-ed ,inwardlybehind the bushing 18 which it is desired to reinove, they will springout and the bevel faces 16 williengage the inner face of this annularbushing. vr1`hen by striking on the ,face-12 of the tool end vith ahammer or the lilfre the bushing 18 is quickly driven ont.

Vtially rectangular in cross-section, the rod being provided withportions. 4extending n diveigingly from the handle forming'portions andflattened to produce spring sections i -irlatly rectangular incross-section with their wide sides opposed, the rod being continuedbeyond the spring sections in short lengths of the originalcross-section, the rod further havingloutwardly bent extremities havingend surfaces normally in the same plane and angularly disposed withreference to the respective axes of said terminal portions.
